Abstract

The invention relates to the cleaning of products and allows improving the quality and efficiency of cleaning by increasing the degree of saturation of the washing liquid with cavitation bubbles and cavities. The installation comprises a hermetic 1 and an additional 2 chambers for the washing liquid, a vacuum pump 3 connected to the sealed chamber, a drive valve 6 for intermittently supplying air to the chamber 1 and a fluid recirculation system. The latter contains a fluid supply line from chamber 2 to chamber 1, which includes a hydraulic pump 7 and a Venturi tube 8, and a pipe 9 provided with a non-return valve for draining pop-up contaminants from chamber 1 into chamber 2. The venturi tube has a mixing chamber attached to the nozzle of a tube of hydrophobic porous material and covering the tube sealed casing. The cavity of the casing pipe 17 is connected in the free space 5 of the chamber 1. When the chamber 1 is evacuated simultaneously by a hydraulic pump 7, the liquid from chamber 2 is fed into chamber 1. The vapor from the free space 5 under the pressure of the pressure in chamber 1 and the venturi passes through the pores of the hydrophobic wall tubes into the channel of the latter and in the form of cavitation bubbles and cavities are guided by the flow of fluid into chamber 1. When valve 6 is opened, cavitation bubbles and cavities in chamber 1 collapse. At the same time, the oily contaminants through conduit 9 are drained into chamber 2. The venturi diffuser is connected to a sealed chamber in the area of the washing liquid. 1 Cpfla, 2 Il. SO with

The invention relates to the field of cleaning products, and specifically to installations for the liquid treatment of products.

The aim of the invention is to improve the quality and efficiency of cleaning products by increasing the degree of saturation of the washing liquid with cavitation bubbles and cavities.

FIG. 1 is a diagram of an installation for cleaning products; in fig. 2 is a diagram of a venturi tube,

The installation contains a sealed chamber 1 filled with washing liquid and an additional chamber 2 connected to the atmosphere, a vacuum pump 3 connected by the suction pipe 4 to the free space 5 of the sealed chamber, a drive valve 6 for periodically supplying compressed air to the chamber and a system for recycling the liquid. The fluid recirculation system contains a fluid supply line from chamber 2 to the chamber, including hydraulic pump 7 and Veiguri tube 8, the output end of which is connected to the liquid zone of the sealed chamber 1, and a pipe 9 to drain pop-up contaminants from chamber 1 into chamber 2, equipped with a check valve 10. The input end 11 of the suction pipe of the pump 7 is located in the zone of clean liquid chamber 2.

The Venturi tube 8 (Fig. 2) contains an active nozzle 12, a diffuser 13 and a mixing chamber 14 located between them, consisting of a cylindrical tube 15 made of a hydrophobic porous material, and enclosing the tube 15 of a sealed casing 16 connected by pipeline 17 with a free space 5 camera 1.

The installation works as follows.

In the process of cleaning products in the chamber 1, a vacuum pump 3 creates a vacuum, at which cavitation bubbles form in the washing liquid of the chamber. At the same time, by the hydraulic pump 7, the liquid from the additional chamber 2 is supplied through the venturi 8 to the chamber 1. The level of the liquid in the hermetic chamber is increased. In the channel of the tube 15 of the Venturi tube 8, a vacuum is created that is much higher than the vacuum in the free space 5 of the chamber 1. Under the action of this vacuum, the steam from the free space through the pipeline 17 enters the hermetic casing 16 and then through the pores of the hydrophobic wall of the tube 15 in the form of a large amount cavitation bubbles enter the channel of the tube 15. The cavitation bubbles are directed to the chamber 1, where they quickly saturate the volume of washing liquid.

A significant part of cavitation bubbles in chamber 1 is increased to the size of the cavity.

When the valve 6 is opened, compressed air enters the free space 5 of the chamber 1. A high pressure is created in the chamber, under the action of which cao-formation bubbles and cavities collapse, ensuring intensive destruction of contaminants on the surface of products. At the same time, under the action of pressure in the chamber 1, the oily contaminants in the upper layer of the washing liquid of this chamber are drained through conduit 9 to the upper part of the supplementary chamber 2. The liquid level in the sealed chamber decreases and after exiting the fluid from the inlet pipe 9, the pressure in the chamber 1 drops to atmospheric.

Then a vacuum is again created in chamber 1 and the cycle is repeated.

The invention allows, by increasing the degree of saturation of the washing liquid with cavitation bubbles and cavities, to increase the quality and efficiency of cleaning products.
